Here in Barcelona and inspired by this thread I established from the Russian lady, who tells me her name is Lydia and is currently standing on the corner of Carrer de Sant Pau and Las Ramblas, that her services are available at EUR 60 for 30 minutes in her room (location uncertain) and at EUR 112 (she might have meant EUR 120) for 60 minutes in my room in a nearby hotel (see my
trip report for pictures from a few years ago, including fully-nude mermaids).
BA's First fares in comparison are typically between EUR 2.5k and EUR 10k for between 20 and 30 hours of fun, or between EUR 123 and EUR 333 per hour. Lydia's fees are comparatively cheap compared with BA's First fares.
Lydia is very beautiful, but after a busy day talking airline and with another busy day expected tomorrow I felt it appropriate to decline.
