We had a great stay at Helena's apartment. The flat is beautiful and so carefully furnished. There is everything you need: coffee, kitchen stuff, cleaning things etc. The comunication also went great. They were very helpful with any request, for example it was possible to checkout late for which we were very grateful for. The area is very lively and centric, there are lots of bars and restaurant. Most of the areas like gran vía or retiro you can reach by foot. Only thing I could mention is that late at night I would have probably felt a bit safer in a neighbourhood a bit more up nord.
