Would definitely recommend this place! It's exactly as it looks in the pictures and description, was clean and tidy when we arrived and easy to find, thanks to Ulrik's instructions. The location is also great, really close to a metro station, and there was loads of things to do within walking distance.
Ulrik is a really good host, so helpful and gives you loads of information about Lisbon (transport, tips, taxi numbers, etc.)! The collection & dropping off of the keys is really easy as they are in a coded box outside and you just leave them in the apartment when you leave. This was really helpful for us as we had a really early morning flight home.
