Our stay at La Casa di Bianca was both very positive and very negative. The location is perfect—in the middle of Trastevere, but on a back courtyard on a side street, where it is really very quiet. The apartment itself is lovely, very nicely furnished, and comfortable (if you like a very firm mattress). However, there was essentially no hot water; the hot water tank never really heated the water beyond about 33 C / 92 F, so we took lukewarm to cold showers all week. The worst part was that the actual owners had outsourced the hosting to a fellow named "Lele", who outsourced the check-in to yet another company, who were professional but said "don't call us about problems with the flat". However, Lele never once responded to our messages once we had arrived, and so the hot water problem was never resolved. It's a pity, because it's really a very nice apartment.
