I have spent one and a half week at Alex and Gemma's place during my research trip to Barcelona. The location was very convenient for to go to Faculty of Biology. The flat is cozy and very fresh and exactly as it looks like. They provide every single detail you need. The internet connection was bad in the bedroom but the rest was fine. We could reach Alex easily via phone. The house is in a nice quiet area. I will definitely consider to stay here again for my next trip to Barcelona!
