This is a small room (not penthouse) that is on the top floor. The patio is bigger than the room. It’s a cute little space, though, and the AC is wonderful!
There is an elevator!
The bed is comfortable.
The patio is nice to use in the morning and evening, but once the sun is up it’s too hot (at least in the summer). It really needs an umbrella so you can actually use the space.
The location is great, close to metro stop Diagonal, 5 minute walk. There’s a placa there that has plenty of restaurants to choose from. There are also two grocery stores close y where you can get anything.
I didn’t cook/use the kitchen much except for the cups because it’s simply too small of a space. I think the space would be better off used to expand the tiny bathroom.
My biggest concern is the bathroom. You’re better off using the sink in the kitchen, as the sink in the bathroom is too small, water gets everywhere. And the shower is simply too small. Good water pressure, but you can barely move around on there: every time I moved I would shut the water off with my body movements. It’s also a little tricky getting in and out because it’s so small, and could be a little dangerous. (I’m 5’8, so average height/build).
Communication is good, but you won’t meet the host. You will meet up with someone else who lets you into the apartment (and others; this is pretty common in BCN, as these are essentially hotel rooms and the owners will usually have multiple apartments and outsource the check ins).
I prefer to stay in apartments than hotels because I like to feel a little bit of the life in Barcelona, and staying in this type of unit you will get that. Great location, plenty of close shops/restaurants, and comfortable place. Just beware of the limited space if you’re a bigger person.
