borja wasnt there for the check in process as we arrived late but a friend of him was there and showed us around. the communication with borja went well from the beginning to the end of our citytrip. he was always available by mail/messenger if we had a question. this was very helpful.
I can fully recommend Borjas studio appartment. it is well-located in the middle of the popular discrict la latina and easy to reach with public transport or taxi. the city center and the sight seeing highlights are in walking distance. la latina is the perfect spot to discover the city of madrid.
the appartment is modern, clean and well-equiped - tv, microwave, kitchen equipment, a hairdryer, a comfortable sofa, towels everything you need is clean and ready to use. there is a aircon too which is good if its hot outside. you can even use the kitchen to cook your own meal - however, we didnt use it, as one of the reasons to go to madrid is defintely their local food culture (tapas). la latina has a lot of restaurants/tapas bar in close distance so try one of them if you are visiting madrid.
in conclusion: if we would come back once we would definitely stay again at borjas appartment.
