We had a nice stay at Martin's place. The location is great. It just took us 20 - 25 mins on average using the subway to reach most of our preferred spots & there were a lot of bars & restaurants a shortwalk away. We didn't really spend a lot of time outside our room but the house had a unique feel to it.
Couple of things I didn't realize initially, the place is much older than I expected and makes a lot of creaky noise. And we had to take stairs for 3 floors every time. Wasn't really a big deal for us but could be for someone else.
Parking was relatively easy to find and we only used the vehicle when checking out. Martin was very prompt in responding to our enquiries and helping out with local information. Overall, we had a really nice stay and would recommend it.
