I would highly recommend Martin's apartment. The location is excellent! It is within easy walking distance to nearby restaurants, a market (Mercado Baixa) and very close to the water. Also the #28 Tram is located 2 minutes down the street. The apartment is very clean and can easily accommodate 4 people. I was there with my girlfriend and it was awesome to have two bathrooms when we were getting ready in the morning. Martin and his associates were very easy to reach and responded immediately. We highly recommend Lisbon and we highly recommend you stay at Martin's apartment.
