I had the pleasure of staying with Matthew for a couple of nights. He certainly went out of his way to be hospitable — especially in his flexibility with check-in and allowing me to store my luggage and check out a bit late. And it was nice chatting with him over breakfast. He even offered to make tea for me, which was lovely.
The room itself was spacious and clean. I appreciated having access to a desk with mirror and a hair dryer. The bathroom was also very clean. The bed was a bit on the softer side, so just be warned. It was very cozy overall, but got a bit cold during the day. The room is several flights of stairs up, so keep that in mind if you happen to have heavy luggage.
As it's explained in the house rules, shoes must be taken off in the entrance. It's certainly a reasonable rule, but the entrance is quite narrow, so it can be a bit difficult if you first get in and are carrying several things (and there is nowhere to sit).
The location is not bad — but it's a bit of a walk to the underground stations. It's nothing crazy — about 10 minutes and a fairly flat walk, but that's probably the least convenient part of this otherwise nice stay. Also, there are some shops near the underground stations, so if you're hoping to pick up something from the market (water or a snack), be warned that they might be closed before you return home for the evening.
