We had a great stay at Matt's place, the apartment is huge, well decorated and there's a rooftop as well. The bedroom was clean, the bed comfortable and regarding the bathroom it was great too. The only issue we experienced during our stay was not because of Matt, but there were construction on the metro line right behind our room. But it was only for two nights. There's also a very friendly and funny dog, you'll like it.
I highly recommend to stay at Matt's apartment which is very close to the sub too !
