Dear friend, if you are reading this announcement now and come to the comments, I advise you to stay with Miguel.
Firstly, it is worth highlighting a very good location. The metro and bus stop where night buses run is really close (within 5 minutes a very leisurely walk). Also within easy walking distance from the station, from where you can get to El Prat Airport and Port Aventura (as well as to many other directions that may be useful to you on your trip), R5 station to Montserrat. Also very close is Plaza de España, the Montjuic fountain. The beach and many major attractions can be reached within one and a half hours, enjoying the views of Barcelona along the way. Nearby there are many cafes and bars for every taste, minimarkets. Very, very near Mercadon (be careful, many shops do not work on Sunday!).
About the house itself. The apartment is very bright and the atmosphere is cozy, nice interior. The toilet and bathroom are very clean, like the whole apartment. The kitchen had everything necessary for cooking. Although when we were visiting Miguel, there was no air conditioning, there was a wonderful fan in our room and we were not hot even with the windows closed (we were in August). The bed is very large and pleasant. Suitable for tall enough people (I am 187 cm) and two people are very freely spaced wide.
Miguel is really a super host! Very nice, open and caring person with a great sense of humor. It was very nice to meet him and Monica, Alina and I had a lot of fun and warm communication with both of you.
Thank you for everything, Miguel!
