It was great to stay at Javier's place. You will get what you expect based on the description. The building is nice. The apartment is on the 7th floor but there is an elevator. It's on a quiet street, so it's ideal also for light sleepers. Also the neighborhood is good. It's safe to wandering around. The location is amazing. There are a lot of bars and restaurants around. Multiple subway lines is in 5 minutes distance, so you can reach everything easily. Soho is 20 minute walk, Time Square is around 1 hour (also by foot, using the subway it takes around 25 minutes). Javier is a great host, he's helpful and totally responsive. The room was ok, and the bed is amazingly comfortable, everything was clean.
Some things to keep in mind. The flat is not big, there are not too much space, which is ok, however be aware if you planning to spend more time in the apartment. The room is actually bigger than it looks on the picture (there is a working-desk also). But still small. The walls are not thick, so privacy-wise it's not the best. I mean for a solo traveler it is good, but for couples maybe not the best. Also there is a kitchen, but there is not too much stuff in there. So you can make a sandwich, or use the microwave but nothing else. Last thing is the keys. The one have to collect it at the beginning of the stay and return it at the end. The key-box is not far away, but not too convenient if you have big suitcases.
Overall it was a great choice. Considering the price/value, it's super good. I would definitely stay again. Thanks Javier to hosting me.
