Marcel was the perfect host and his place is great. First, the location is the perfect base camp for exploring the city. We walked everywhere with no issues. There are several good restaurants, canal cruises, and other popular tourist spots within a 5 min walk.
The room was ideal for us with our own bathroom, comfy bed, rooftop balcony, and access to the kitchen and common areas. There is only 1 other room in this apartment so you're sharing the balcony and other areas with them, but everything is plenty big enough for several people. For example, the rooftop balcony has 3 separate sitting areas - a 4 person table/chairs and 2 separate lounge areas. The evenings were lovely up there with a view of the clock tower, surrounding buildings, and open sky. There are 2 plugs per side to charge your devices.
The shower/sink is attached to the bedroom and the toilet (with about sink) is just outside but each room has their own. Marcel lives in the apartment downstairs, so he was always available for questions. He's a very knowledgeable local and was happy to point out the best restaurants and advice on getting around. The weather was a little on the warm side while we were there, which was uncharacteristic for the area, but it was never a problem. We're used to A/C at home but still slept well here. The room has 2 large windows which open, giving a nice breeze during the day (if you leave the bedroom door open) and a small fan to stay cool at night if you want the bedroom door closed.
Highly recommend this place!
