We spent several days in Andrei and Alina's apartment during our visit to Barcelona.
(+):The host was always in contact with us, so we could ask or adjust our plans very fast and convenient. The apartment was big enough. Not far away subway two stations, train station and bus station are easily accessable. The apartment is big and pretty clean. We were seven persons (all girls), 2 of us had to sleep in the living room. But it was fine for us. Air condition worked perfectly. Check-in went fast.
(-): We had not enough of toilet paper for 7 persons. It would be also nice to have more kitchen towels or paper towels. But it's all minor details.
