I haven't stayed at the RC or Suiran, but stayed at the FS Kyoto last month. All e-mails to concierge were responded to within 24 hours and they booked all the restaurants I requested - although it should be noted that I didn't ask for any of the typical hard-to-get spots, as to be frank I've never had a good experience at any of the famed / 3* / etc. places in Kyoto. As is typical with Japanese hotels, they do require a signed CC authorization form for restaurant reservations (fortunately, unlike MO Tokyo's inept concierge, they do not demand scans of the front/back of a CC). Detailed directions to and storefront images of all restaurants they reserved were waiting in my room on arrival.

While I'm posting, might as well give a few brief details for review purposes. I contacted the hotel directly for booking as FHR had not loaded 2018 properties yet. They basically gave me an Executive Suite at approximately the rate for a Premier Room and also included breakfast at Brasserie. They further upgraded me to a 1BR residential suite on arrival. A bottle of champagne was also waiting in the room. Granted 3pm checkout request (late checkout was not pre-arranged with the booking). All of this may be due to the slow season, as the property seemed very quiet during my stay - I saw maybe a dozen other guests during my entire time there.

Room was good. I liked the furniture and finishings - it's a new hotel, so obviously everything is in top shape. Huge closet area, although it is a walk-through type in front of the bathroom. Large combined shower/tub area. The residential version of the 1BR also has a combo washer/dryer in-unit. Nitpicking a bit, but the rooms are rather narrow and full of furniture so the suite didn't feel that spacious; more of a cozy vibe. For the price I paid, no problem - but I don't know how I'd feel if I were paying the 150,000¥++/night regular rate. Housekeeping was good and consistent; I also liked that 6 bottles of water (or maybe 8, can't remember) were provided and restocked at both main service and turndown.

The hotel grounds are stunning. The pond garden is gorgeous and during warmer weather, the garden terrace would have been a fantastic place to spend time but it was bit cold during my stay. I also greatly enjoyed Shakusui-tei, an old tea house across the lake that serves champagne and sake from 5-9pm; we even got a visit from a geiko to play drinking games.

I want to try Suiran at some point, but would certainly look to stay at FS Kyoto in the future. Also, it's not that poorly located; it's an easy, 10-minute downhill walk to Shichijo station. Since I'm lazy, I'd typically walk downhill to Shichijo when leaving the hotel and taxi on the way back. The hotel is also right next to the Kyoto National Museum.

EDIT TO ADD: If you plan on taking taxis from the hotel, I recommend pre-booking taxis via the concierge if you're on a schedule - otherwise, expect at least a 5-10min wait for taxis.
