Stayed there in January in the Boutique Hotel owned by the guys who run the Sagardi restaurant and Tapas Bar

Excellent place, plenty to eat and upstairs to sleep!

Yes, I was pleased to see Sagardi reopened.

No he’s a Porteño

Yip but new management, I see. I knew one of them quite well but he left during the pandemic

Still one of the waiters recognized me - You are the Scottish guy from Zona Norte, Right? Still drinking Imperial IPA?

I hadn't been in for two years!

We are in BA now, and have ben here since end of February. Went to Montevideo, so our 90 day clock re-started. So far, Subway easy to master. Buses, well, we finally got brave. So far we have taken the bus from the BuqueBus terminal ( after the ferry back from Montevideo) to our apartment. We took the bus to Boca to check out La Bonbonera and took the train to Tigre. We watched the little blue dot on our phone maps as we travelled on the bus. Got off on one stop too early the 1st time, but exact the 2nd. Rome2Rio tells you which bus, and the stop. When you board, you tell the driver your stop, and he pushes a button to the # of stops it is and you zap you Subte card against the machine. And you push the orange button on the pole for the alert for the next stop. We are going to Iguazu beginning of May. We are going to bus to/fro AEP!!
We are in an apartment in Recoleta. Love it here!!!!

You'd probably get more and better information by posting your question on Trip Advisor in the forums.

Has anyone here been to Montevideo before? Is it open to fully vaccinated Americans? What do I need to know about going there from Buenos Aires? Fast or slow ferry? Possible just to go there for a day trip?

Check SeaCat cheaper than Buquebus also the Uruguayan site is cheaper than Argentina yes you could do a day trip if you’re going just to Colonia but why not spend a night or two in Montevideo. The boats stop at Colonia you could spend the day and then you have a pass for the bus to take you to MVD

I think the people on FT will take offense to that🤓

Google maps on your phone works fantastically for the bus. Will even give you walking directions to the stop, etc.

The first thing is that I'm now officially pissed for not pulling the trigger on the UA fare earlier, as it went formally up over $100 today. :(

The second thing is that I will have about three full days if I go to Buenos Aires. I'm thinking of two full days in Buenos Aires itself and one full day in Montevideo. Is that enough? How long is the ferry?

Thank you.

Three days is a short amount of time to spend in Buenos Aires. I wouldn’t even consider Uruguay for this trip. Remember the old FT adage book now, think later. You always have 24 hours to make up your mind if you want to cancel. Prices are fluctuating google flights works well. But to be quite honest you’re asking a lot of information for three days

What do you mean by too much information over three days? I can't travel for more than a week, including travel time anyways. Often I end up having to make multiple trips to the same destination in the same year. I'm not going to explain a lot of things for privacy reasons. At the end of the day, the more information I get, the better my decision will be on how I should spend my time. No better way to get the best information than to ask FTers here.

As someone who, when I started frequent travel, had little time for long trips, I am familiar with repeat trips to the same places.

That said, I'd skip Uruguay. It just creates another level of hassle and travel time in a very short trip. If you do consider a day trip to Uruguay, I'd suggest nothing more than Colonia. MVD will kill an entire day, with much of it on a boat and terminal - and lest one forget, early arrival at the terminal for international processing.

The ferry is 99 meters long ;) :D
