I was traveling solo for four nights in Valencia and Maria's flat was perfect for me. It is indeed small, but has everything you can need. The location is perfect—walkable to pretty much everything, including a Metro stop. The balcony is a fantastic place to have morning coffee or an evening drink and listen to folks below, including an occasional busker. The street is lively, but not too loud, so noise was not an issue. I had a couple of questions for Maria during my stay and she was very prompt in answering.
