I didn't get to meet Montserrat but her son was very nice and professional as he explained everything to us. The house was very clean and comfortable. It has everything you need, from any kitchen utensil you can imagine, to a very efficient washing machine! The wifi connection was great. The neighborhood was very nice as well and it has two metro stations that are about 5 minutes walking.
Montserrat responds very quickly to messages and she was very helpful and flexible.
